Looking for plans for a 2 meter preamp which I intend on using for
144MHz SSB/CW work. I would like it if the plans should also be able
to handle 100 Watts from the tranceiver.

Thanks
George

There are lots of published designs for low noise
preamps for 2M. The Mitsubishi MGF1302 seems to
be the most popular device for homebrew VHF/UHF
preamps. I use the MGF1302 in my preamps for
2M, 70CM and 23CM.


Use your favourite search engine to search for:
low noise GaAsFET preamp for 2M

See YU1AW's excellent designs at:

See W5UN's MGF1302 preamp at:

It must be very good because he can sometimes
hear my puny 250W to a single 9 element Yagi
on EME.

For high power on VHF, you should use good
quality co-ax relays and a sequencer.

The ARRL handbook has some good designs for
2M preamps and an RX/TX sequencer.
